I passed on the iOS 6 update. My jailbreak already gives me most of that functionality and more.
Just FYI for those of you that haven't tried jail breaking. It's free, completely reversible, and you can't brick your phone. It's win-win. So many cool apps for free that allow customization like an Android phone. Go to green poison website to get for free. Can't recommend it enough.
Yea, I think I'll jailbreak the 3GS this weekend before turning it over to the kids.
